CHARLES F. SMITH, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO LANDERS,FRARY & CLARK, OF NEW BRITAIN, CONNECTICUT, A CORPORATION.

PERCOLATOR-COVER.

Specification of Letters Patent.

Patented Jan. 3, 1911.

Application filed July 7, 1910. Serial No. 570,739.

To all whom it may concern:

Be it known that I, CHARLES F. SMITH, a citizen of the UnitedStates,residing at New Britain, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inPercolator-Covers, of which the following is a specification.

My invention relates to improvements in percolator covers and theobjects of my invention are simplicity and economy in construction andefficiency of the article, particularly with reference to a durabletransparent cover.

In the accompanying drawings :Figure 1 is a plan view of my percolatorcover. Fig.

2 is a sectional view of the same on the line as w of Fig. 1. Fig. 3 isa plan view of my percolator cover on a smaller scale and in a modifiedform.

While the cover herein shown and de scribed is specially designed foruse as a percolator cover, it is evident that it may be used as thecover for any other article that it is adapted for.

The cover comprises a metal frame or support and a glass or transparentdome mounted on thesaid frame.

A designates the metal frame the base of which is provided with a rim 4:and flange 5 designed to fit the top of a percolator. Extending upwardlyfrom the rim 4 there are three arms 6, which curve upward and inwardtoward the center where they are united in a centrally perforateddome-holding disk 7 that is preferably made in one piece of metal withthe rest of the frame A. The several arms are provided withlongitudinally extended hollow ribs or beads 8.

B designates a dome, of glass or equivalent transparent material, whichis preferably made rather thin for glass and is provided with a bottomrim 9 that is designed to extend under the inner edge of the base rim 4at the openings between the arms 6. The upper part of the dome isprovided with a hollow boss or projection 10 that is designed to bereceived by the dome-holding disk on its underside. A cupped washer 11is placed in the center of the dome on the inside where it and the domeare secured in place by a screw 12 that passes up through the saidwasher and the dome-holding disk into a threaded hole in the knob 13,which knob may be of any suitable material, preferably non-metallic.

The same general construction is shown in Fig. 3, only the frame A isprovided with but two arms 6 instead of three, the said two arms beingunited at the center by the dome-holding disk 7, all the other parts Ybeing the same as herein first described and designated by the samereference characters.

As described it is evident that the arms 6 and 6 constitute means forsupporting the dome holding disk upon the rim of the frame.

It is apparent that some changes from the specific construction hereindisclosed may be made and therefore I do not wish to be understood aslimiting myself to the precise form of construction shown and described,but desire the liberty to make such changes, in working my invention, asmay fairly come within the spirit and scope of the same.

By my invention the liquid that is forced up by the percolator fountainmay be readily seen through the dome and its operation watchedsubstantially the same as if the cover were formed wholly of glass. Theglass or transparent dome has its central portion connected with thecentral domesupporting disk and the weight of the said dome istransmitted through the said central portion to the said disk, then tothe arms, and then to the base rim. The base, which is the largest partof the dome, is entirely free from all other parts of the frame, isnever seated upon any object and need not have contact in any way withany other thing. The glass dome may be thin as compared with a coverwholly of glass whereby the complete cover is or may be lighter than anordinary glass cover. The dome may be made comparatively thin instead ofthick and heavy, because the frame protects it against breakage byconcussion and by being thin it is less liable to break by reason ofunequal expansion when rapidly heated.

The complete cover presents a neat and attractive appearance and theknob may be of a non-conducting material so that it will never beinconvcniently hot.

The article can be produced at a small cost and is very efiicient anddurable.

I claim as my invention:

1. A percolator cover comprising a metal frame having a base rim, adome-holding disk at its center, and means for supporting said disk onsaid rim a transparent dome having its central portion connected Withthe said disk, and means for holding the said dome and disk together,whereby the Weight of the dome is transmitted through its centralportion to the said disk and finally from the said disk to the base rimof the said frame.

2. A percolator cover comprising a metal frame having a base rim, acentral domeholding disk, and means for supporting the said disk on thesaid rim, a transparent dome mounted on the innerside of the said frame,a knob at the center on the outer side of the said frame and means forholding the said dome and knob in place on the said frame.

3. A percolator cover comprising a metal frame having a base rim, acentral domesupporting disk, and a plurality of arms, With open spacesbetween, by means of Which arms the said rim and disk are united, atransparent dome on the inner side of the said arms and means forholding the said "dome in place on the said frame.
